Julian Schnabel made an unusual shout-out at a recent screening of his acclaimed 2007 drama “The Diving Bell and the Butterfly” — to an audience member he dubbed “probably the only cousin I love,” a spy said.

During a Hamptons International Film Festival at MoMA Q&A, Schnabel pointed out the relative, “80-year-old Dr. Jesse Blumenthal,” the witness said. Blumenthal is the former chief of trauma services at St. Vincent’s Hospital, and Schnabel recounted that he “took care of” his mom and “kept her alive an extra 13 years.”
